If you want to build a case statement that represents every possible combination of two consecutively entered characters, that is going to be a very big case statement.
If, for example, the keypad has 16 keys, that is 256 possible entries.
this is true, my keypad is only 4x3, and if i only have cases up to 25, im sure there is a way to return a error should a case other then that be attempted to be entered.
Any advice?
